Subject: [PATCH] cmake: increase threshold for stack probes
The /Gs argument controls the number of bytes that local variables
can occupy before a stack probe is initiated.
By setting it to a huge value, no calls to __chkstk are inserted.
This change is needed for the classic Intel C compiler to build SDL
with -DSDL_LIBC=OFF.
